Why does the directory grouping changes of empty servers tag does not persist in host.xml ?

Issue

• There is an issue with the directory-grouping configuration. Following are the steps how to reproduce this behaviour:

  • Started JBoss in domain mode.
  • Removed the default servers as follows:

  /host=master/server-config=server-one/:stop
  /host=master/server-config=server-one/:remove
  /host=master/server-config=server-two/:stop
  /host=master/server-config=server-two/:remove
  /host=master/server-config=server-three/:stop
  /host=master/server-config=server-three/:remove
  

  • Edited the directory-grouping configuration from "by-server" to "by-type".

  /host=master/:write-attribute(name=directory-grouping,value=by-type)
  

  • Then added a new server to the configuration, now the directory-grouping attribute will be again set as "by-server" ( which is by default value) and not "by-type". So when all the servers are removed, then the directory-grouping attribute setting is lost.
  • Also noticed that when all the predefined servers are removed, then the <servers> tag is not present anymore in the host.xml.
